lumbar plexus

Similar to lumbar plexus there is brachial plexus in upper limb.

Spock has some level of damage to thirty percent of those, mostly in his lower thoracic area and lumbar plexus.

The iliopsoas is innervated by the femoral nerve and direct branches from the lumbar plexus.

The lumbar plexus contains ventral rami from spinal nerves L1-L4.

The first three and the greater part of the fourth are connected together in this situation by anastomotic loops, and form the lumbar plexus.

It communicates with the iliohypogastric nerve of the lumbar plexus, and gives a branch to the Pyramidalis.

The lateral cutaneous nerve of the thigh is a nerve of the lumbar plexus.

The femoral nerve (L2-L4) is the largest and longest of the nerves of the lumbar plexus.

In human anatomy, the 'genitofemoral' nerve originates from the upper part of the lumbar plexus of spinal nerves.

The nerves of the lumbar plexus pass in front of the hip joint and mainly support the anterior part of the thigh.

The lumbosacral trunk is nervous tissue that connects the lumbar plexus with the sacral plexus.

In 1931, Aburel was the first to describe blocking the lumbar plexus during early labor, followed by a caudal epidural injection for the expulsion phase.

The ventral rami of L1-L5 spinal nerves with a contribution of T12 form Lumbar plexus.

Often, the sacral plexus and the lumbar plexus are considered to be one large nerve plexus, the lumbosacral plexus.

The lumbar plexus is a nervous plexus in the lumbar region of the body which forms part of the lumbosacral plexus.

Since the Lumbar plexus and Sacral plexus are interconnected, they are sometimes referred to as the Lumbosacral plexus.

The arteries of both sides pass beneath the tendinous arches which give origin to the Psoas major, and are then continued behind this muscle and the lumbar plexus.

The four primary nerve plexuses are the cervical plexus, brachial plexus, lumbar plexus, and the sacral plexus.

The other thoracic nerves remain individual, but the lumbar nerves join to form the lumbar plexus, and the sacral nerves form the sacral plexus.

The signal will travel through the anterior root of L4 and into the anterior rami of the L4 nerve, leaving the spinal cord through the lumbar plexus.

The lumbar plexus is formed lateral to the intervertebral foramina by the ventral rami of the first four lumbar spinal nerves (L1-L4), which all pass through psoas major.

The femoral nerve, the largest branch of the lumbar plexus, arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2-L4).

The obturator nerve leaves the lumbar plexus and descends behind psoas major on it medial side, then follows the linea terminalis into the lesser pelvis, and finally leaves the pelvic area through the obturator canal.

Based on distribution and topography, the lumbosacral plexus is subdivided into the lumbar plexus (T12-L4) and the Sacral plexus (L5-S4); the latter is often further subdivided into the sciatic and pudendal plexuses:

The psoas major is innervated by direct branches off the lumbar plexus at the levels of L1 and L2, while the iliacus is innervated by the femoral nerve (which is composed of nerves from the anterior rami of L2-L4).
